To the theory of the migration current depression in electrochemical systems

The problem of the metal dissolution and the simultaneous cation discharge from a binary electrolyte is discussed theoretically. Analytical formulas a re obtained for the limiting current of the cation discharge as a function of the electrode dissolution current, and for the distribution of concentra tions of solution's components and electric potential in the diffusion laye r. In the system involved, the limiting current of the cation reduction dec reases drastically with an increase in the current of the parallel process of metal dissolution.
